In the first three years of Emperor Jing of the Han Dynasty (154 BC), the second month of spring and the day of Jiayin.

The temperature in Chang'an began to warm up rapidly.

Spring has finally arrived.

As usual, on this day, the emperor ploughed the fields himself as a sign of heavy farming.

Of course, it's just a symbolic engagement, a performance.

Just like some leaders in later generations who planted trees on Arbor Day, they just buried some soil and didn't really dig pits and plant trees by themselves.

In Weiyang Palace, there is a piece of land, about one acre and three points of land.

Every year, the emperor's pro-ploughing program is held here.

At this moment, as in previous years, Emperor Jing of the Han Dynasty was standing in the middle of the field, holding a plow in his hand, digging a pit in the ground.

Then, he put in the seeds, buried some soil, watered some water, and the show was over.

Later, someone will be responsible for continuing to cultivate the land until the harvest is completed.

After the grain harvest, Emperor Jing of the Han Dynasty will also use the grain produced here to sacrifice the ancestors and Sheji.

When Emperor Jing of the Han Dynasty was digging a pit in the field, Empress Bo planted a mulberry tree on the side.

It's one of the few times of the year when two people get along.

The implication of planting mulberry trees is also obvious, that is, attaching importance to silkworm raising and weaving.

In feudal society, agriculture was generally valued, and the emperor and empress personally performed male ploughing and female weaving, in order to inspire the peasants of the world to work hard.

As in previous years, Emperor Jing of the Han Dynasty had to make the next edict on agriculture.

This edict will be transmitted to the grassroots level of the Han Dynasty through a nationwide transportation network, so that every Han citizen will know its meaning.

His edict said: "The road of the people lies in the business, and the people are hungry if they do not climb the year." I personally led the world to farm for Zongsheng, and the queen pro-mulberry for sacrificial clothes. Under the edict, the people are advised to cultivate and weave, and they are diligent. ”

。。。。。。

With the issuance of this edict, today's performance should have come to an end.

Who would have thought that at this time, Liu Rong suddenly ran out and stopped Emperor Han Jing.

Emperor Han Jing was stunned for a moment, his face full of question marks.

What are you doing kid?

Liu Rong smiled mysteriously and said:

"Father, two months ago, you asked your retainers to pay more attention to farming, and your retainers always keep it in mind."

"In recent days, Erchen has read many suicide notes of ancient sages, visited many old folk farmers, and worked hard to study and improve agricultural tools in order to increase grain production."

"Today, the father and the queen mother personally cultivate and weave, and they are models for the world. Erchen wanted to take this opportunity to dedicate some of the most efficient farming tools he had recently developed to his father. ”

"Erchen has already carried out experiments, and these farming tools work very well, which can greatly improve the efficiency of cultivation and save manpower."

"If it can be popularized on a large scale, this year's grain output in Dahan can be conservatively increased by 30%."

When Emperor Han Jing heard this, he glanced at Queen Bo, and his eyes were full of disbelief.

What kind of farm tools, so useful, can actually increase the grain output by 30%?

Impossible, never.

How did this son of his own learn to brag and lie?

How did he know that Liu Rong was still hugging.

If all the Han could use his farming tools, a lot of land that could not be cultivated in the past would be turned into fertile soil, and the grain output would be doubled.

Empress Bo looked at Liu Rong in front of her, pondered for a while, and said:

"Your Majesty, I know this kid Rong'er, come quickly and be cautious, and never say big things."

"Why don't we take a look at his new farm tools, and see if these farm tools are really as magical as Rong'er said, and the concubine is really a little curious."

Empress Bo is speaking for Liu Rong.

Liu Rong was secretly proud, his efforts these days were not in vain, and Queen Bo had already begun to stand in line with herself.

She has no own sons, and her attitude towards the princes is no different.

Liu Rong is the oldest, has the greatest chance of inheriting the throne, and frequently shows her goodwill, so she is naturally willing to be close to Liu Rong.

In this way, if Liu Rong can really succeed to the throne in the future, she will be able to continue to enjoy wealth and prosperity.

Why not?

After listening to Empress Bo's words, Emperor Han Jing nodded and said:

"Let's go, let's take a look."

。。。。。。

So, Emperor Jing of the Han Dynasty and Empress Bo, with civil and military officials, came to Liu Rong's first hall.

I saw that the courtyard of the first hall was full of all kinds of farm tools, strange shapes, and I had never seen them.

When Emperor Han Jing saw it, he was immediately interested.

Liu Rong beckoned and called Ding Huan over.

Although Ding Shu is proficient in machinery, he is ignorant of human feelings and is a typical engineering man.

Now, once so many high-ranking officials have arrived, there is already a bit of timidity in my heart.

He trembled and knelt down in front of Emperor Han Jing and kept kowtowing.

Liu Rong introduced:

"Father, this person's name is Ding Xuan, known as Sailuban, and he is the world's first-class craftsman."

"Now he is responsible for building most of these farm tools. Let him introduce you to these farming tools. ”

Hearing this, Emperor Han Jing nodded.

He had never heard of such a skilled craftsman in Chang'an.

Seluban, hehe.

Seeing that this person is not very old, can he compare to those experienced craftsmen in Shang Fang?

Emperor Jing of Han was a little skeptical.

Liu Rong turned his head to face Ding Shu and ordered, "You can introduce these farm tools to Your Majesty." ”

When Ding heard this, he said yes again and again, and got up from the ground.

。。。。。。

First of all, Ding slowly walked up to a horse-drawn cart-shaped farm tool and introduced:

"Your Majesty, please see, the name of this thing is called Wooden Ox Flowing Horse, it does not need the power of oxen and horses, it is only carried by manpower, it can carry a thousand catties, and it can walk like flying."

Emperor Han Jing frowned, with an expression of "really, I don't believe it", and said: "It's just such a small thing, can it carry a thousand catties?" ”

Liu Rong smiled beside him and said, "Father, can or can't, let's just try?" ”

He saw Wei Qing and his gang in the crowd, so he beckoned Wei Qing, Gongsun Ao, Gongsun He, Zhang Cigong, and Su Jian to come over.

On the one hand, it was to let them help test the load of the wooden ox and flowing horse, and on the other hand, it was also to give them the opportunity to show up in front of Emperor Jing of Han.

Liu Rong instructed a few people, "You go and move a thousand catties of corn quickly." ”

When the five of them heard this, they hurried away.

It didn't take long for them to return.

I saw five people stretching out ten hands, each carrying a sack weighing 100 catties.

Each person only relied on his hand to get 200 catties of grain at one time.

Several people walked like flying, lifting weights like frightening, like pinching small candy, without any effort, and the atmosphere was not breathing.

Seeing this, Emperor Han Jing nodded, "These five people are really warriors." ”

Seeing this, Liu Rong was very proud.

Immediately, he ordered several men to pile the sacks on top of the wooden oxen and horses.

Thousands of pounds of grain, piled up on top of the wooden oxen and horses, formed a small hill, as if it would crush the machinery below at any moment.

Everyone couldn't help but wonder, this monster was crushed by the mountain, can it still move forward?

Liu Rong smiled confidently, glanced at Ding Huan, and motioned for him to urge the wooden ox to flow the horse.

He wasn't very tall, and he even looked a little weak.

Letting him control the wooden oxen and horses and transport thousands of catties of grain is far more shocking and convincing than letting a strong man like Wei Qing and them come.

。。。。。。

I saw Ding Chu standing on the wooden ox and flowing horse, spit on each of his hands, and rubbed them to increase the friction of his palms and better control the machinery in front of him.

His body slowly squatted, his hands resting on the mechanical arm, and then slowly got up.

The grain on the wooden ox flowing horse actually rose smoothly with it, and there was no sign of falling.

Everyone's eyes suddenly lit up, this machine is not simple.

Then, Ding slowly began to exert force, trying to urge the wooden ox to move forward.

The wooden oxen and horses moved slowly, and the sack on it began to crumble.

The hearts of the people rose to their throats at once.

I saw Ding take a deep breath and stride forward, and the wooden ox and horse drove out, and although the sack swayed, it finally did not fall.

Ding took two steps slowly, step by step like a minion, like the pace of the devil.

His boots rubbed against the smooth floor, speeding up as the Oxen and the Horse went faster and faster.

Everyone's eyes widened, and all kinds of emotional tones blurted out.

"X, that's amazing."

"X, it's actually getting faster and faster, this wooden cow flowing horse can really do."

"X, yes, with the power of one person, you can easily transport thousands of catties of grain, and the use of this thing is probably not limited to agriculture, if it is used to transport military rations-"

"His Royal Highness Rong is talented, this is the artifact of Zhenguo."

Liu Rong listened to everyone's praise and was very proud.

But he was humble on the surface.

Ding slowly pushed the wooden ox and the horse, turned around the courtyard three times, and then stopped smoothly at the starting place.

His body was not as strong as Wei Qing and the others, so he turned around a few times, and his breathing was actually a little short.

Emperor Han Jing looked at the wooden ox and flowing horse in front of him with burning eyes, like a treasure.

"Rong'er, you really surprised your father. Tell me what this is all about, how such a small machine can have so much strength. ”

Liu Rong smiled, took out a stack of thick drawings from his arms, flipped through them, and took out the design drawings of the wooden ox and flowing horse.

Then, he carried out a simple popularization of science in a language that Emperor Jing of Han could understand.

However, from the "wise" eyes of Emperor Jing of the Han Dynasty, Liu Rong could see that he obviously did not understand the principle.

However, although Emperor Jing of Han did not understand, he was greatly shocked.

He looked at Liu Rong's eyes and became extremely loving, good boy, worthy of being my son.

。。。。。。

After seeing the wooden ox and flowing horse, Liu Rong took Emperor Han Jing to continue to move forward.

This machine is just an appetizer, and the real goodies are yet to come.

The second piece of farm implement, the cocoon, is used for sowing seeds.

In this era, the way of sowing seeds is still relatively primitive, and it is all over as soon as it is sprinkled on the ground.

In this way, the loss of seeds is high and the germination rate is very low.

To cultivate more seriously, you dig a pit in the ground, put seeds in it, and then cover it with soil and step on it.

Emperor Jing of Han cultivated like this just now, but the efficiency of cultivation was very low.

The grain grown in this way is a mess, not a column, and it is very inconvenient to take care of.

In this era, although there is already a simple cocoon, it is inconvenient to use, it is a waste of seeds, and it is not as good as manpower to save trouble, so only large families will use it.

And the building car invented by Liu Rong has a cocoon box on it, which can store seeds.

This thing, with three legs underneath, can plant three rows at a time.

The shape of each foot is very peculiar, and it can complete all the operations of breaking the soil, ditching, sowing and covering the soil.

It is also very convenient to use the cocoon, only a cow needs to be pulled in front, and one person can straighten the cocoon, and the seeds in the cocoon box will fall evenly in the ditch along the three feet of the cocoon.

The original cultivation method was to sow a maximum of three or five acres of land per day, and a maximum of more than ten acres of land.

Instead, with the cocoon car invented by Liu Rong, one hectare of land can be cultivated in a day, and the efficiency has been increased by more than ten times.

Listening to Liu Rong and Ding Zhuan's explanations, Emperor Han Jingdi's eyes became "wise" again.

Such a simple machine can improve the efficiency of farming dozens of times?

Liu Rong said confidently: "Father, let them take the cocoon to the field, don't you know it as soon as you experiment?" ”

Emperor Han Jing nodded, indicating permission, he came to see if this thing could work.

The little officials hurried to the field with the cart.

The area of the field is about one acre, and they used this new type of machinery to complete the entire sowing work in just one cup of tea.

When they returned to Emperor Han Jing, Emperor Hanjing's eyes almost fell to the ground.

"What, sowing in such a short time?"

It's incredible!

Liu Rong said, "Father, this is the first time they have come into contact with this kind of thing, if they can operate it proficiently, the time will be fast." ”

Emperor Han Jing took a deep breath and instructed Tao Qing beside him:

"Prime Minister, this thing is very important, you urge Shaofu Shangfang to rush to make it overnight, and this spring, I will promote it on a large scale in the Inner History area."

"If the effect is good, it will be promoted nationwide next year."

When Tao Qing heard this, he hurriedly agreed.

He secretly glanced at Liu Rong, his eyes were very complicated, and he couldn't say whether he was in admiration or awe.

。。。。。。

After that, Liu Rong took Emperor Han Jing to see the keel waterwheel.

This is an irrigation agricultural tool, which is stepped on by manpower to drive the gears to rotate, and the gears can drive the planks to pull the water from the low places to the high places.

As we all know, crops can't do without water.

Much of the land in the world is too high to draw water and is deserted and cannot be cultivated.

With the keel waterwheel, this problem will be solved, and the number of farmland in Dahan will be greatly increased.

In addition, Liu Rong also introduced many machines to Emperor Jing of the Han Dynasty, such as Quyuan plow, rice transplanting horse, Quyuan plow, etc.

Some of them are very suitable for use on small plots of cultivated land, some can greatly save manpower, and some are flexible and can be operated by one person without animal power.

It took most of the day for Liu Rong to introduce his inventions to Emperor Jing of the Han Dynasty.

At first, Emperor Han Jing was still very excited.

I was much more excited in the back, and I was a little numb.

There was no other reason, Liu Rong gave him too many surprises, and he couldn't digest them at all for a while.

Emperor Han Jing looked at his son in front of him, and his heart was surprised and delighted.

This kid, shouldn't he be the reincarnation of Shennong!
